Veteran Welsh prop Adam Jones has been replaced by Scarlets man Samson Lee for the Nelspruit Test and club teammate Josh Turnbull is in for Aaron Shingler at flanker, after both appeared from the bench in last week's encounter.

Those are the only two changes that Gatland has made to his starting team for the second Test despite rumours that scrum-half Mike Phillips might be in danger of losing his place to youngster Gareth Davies after a poor performance last week.

The 31-year-old British and Irish Lion had himself admitted to feeling under pressure, per BBC Wales Sport:

Gatland said of the changes to his squad, per BBC Sport: "It's a great opportunity for Samson and Josh. They deserve the chance after impressing last weekend."

In the Springboks side, Victor Matfield is set to become the most-capped Test player in the history of South African rugby when he leads out his side on Saturday for his 112th appearance.

Heyneke Meyer’s side can wrap up a series victory with a win or a draw and South Africa have also made two changes for the encounter.

Tendai Mtawarira comes back into the front row while Flip van der Merwe joins Matfield at lock, Gurthro Steenkamp and Bakkies Botha both take their places on the bench.

Meyer highlighted the importance of keeping a winning side in similar shape, hence his move to not shuffle too many men out, per Sky Sports:

I've always preferred to stick with a winning combination and the changes to the team were both part of our planning.

The backline really performed well last weekend and we would like to give them another opportunity to play together, as there were a number of new combinations.

The same applies upfront. Bakkies is fit for selection, but we decided to manage his workload this week and I know Flip, who has been outstanding in the last two seasons, will slot back in easily. The same goes for 'Beast', who upped the tempo with his work rate last weekend.

Wales are in for quite a challenge to improve upon a weak performance for the majority of last week's game, but they do have the quality to cause the Springboks some problems.

Dire Southern Hemisphere Record

In the recent past, Wales have a terrific record in European international rugby having won the Six Nations in two of the last three years, with one of those victories being a Grand Slam.

However, the opposite is true of their record against the southern hemisphere giants of South Africa, New Zealand and Australia.

According to Paul Rees in The Guardian, Wales have only two wins and a draw in 53 Test matches against these nations in the professional era.

This is a major concern, especially in the lead-up to next year's World Cup in England, and a win against South Africa is vital in preparation for that 2015 tournament.

It is all well and good winning the Six Nations, but consistent failure on the world stage is unacceptable for a nation of such rugby enthusiasts.

Wales have the quality to beat the southern hemisphere teams—they made up the vast majority of last year's Lions victory in Australia.

They must prove as much on Saturday if they have genuine ambitions of going deep in next year's World Cup. Gatland needs to fix this problem and there must be no repeat of last Saturday's result.
